After reuniting to collaborate on two tracks together and then apparently having a falling out and sub-tweeting about each other on Twitter, Chris Brown and Rihanna came face to face at Hollywood nightclub, Greystone Manor. According to several sources inside the club, the two exchanged dirty looks all night and never interacted. Brown was there with his girlfriend, and Rihanna was at the club with her girls. Check out the full recap of their unfortunate run-in according to Page Six below:

Rihanna and her ex Chris Brown — with his girlfriend Karrueche Tran — came face to face at West Hollywood club Greystone Manor on Sunday, where spies tell us they “shot dirty looks” at each other during the night. The run-in occurred after months of targeted tweets, online feuding and a few other close encounters. At the club’s weekly “urban” night, Brown and Tran partied at a table with The Game, drinking Ace of Spades Champagne. RiRi arrived shortly after with friends, and sat with comedian and actor Kevin Hart at a table near the DJ booth, overlooking the dance floor where Brown and Tran were sitting. A spy told Page Six, “Chris and Rihanna sat a few tables away from each other and shot dirty looks at each other all night. No one saw them actually interact. Rihanna was escorted to the bathroom multiple times and walked by Chris’ table each time, not even batting an eyelash.”
